Acoustic Blanket Installation to Create a 4-Side, Floor Mounted Enclosure. Using our Acoustic Blankets to construct a 4-sided noise control solution will significantly reduce sound. The noise reduction to be expected is a range of 20 to 40 decibles. The better the construction, weight of blankets and amount of acoustic blankets used (the surface area) all factor into your sound reduction numbers. Ensuring all corners and edges are tight, and that there are no gaps is a major factor. The size of the blankets in which the amount of surface area that is available to dissipate and contain the noise is the other major factor.

Acoustics studies the sound and how it behaves in various environments. Sound effects such as absorption, reflection, refraction or interference are also studied by acoustics. The broad acceptance of the term ‘acoustics’ refers to all the aspects of sound. Until not long ago, the notions ‘acoustics’ and ‘sound’ referred to waves and elastic vibrations that humans could hear. However, in the twentieth century, the development of technology and science has led to the broadening of the field of acoustics, in that it now comprises aspects not directly related to the hearing process, such as intensities and frequencies which are above or below the audible limits of humans.

Sound is vibration transmitted through a medium. When we think and talk about sound, though, we mean those vibrations in air molecules that can be picked up by human ears.

Read a little about what the terms mean or dive rightinto our acoustic products on the right. So what does it all mean? All soundproofing and noise control terms cover a lot of ground in the acoustics and noise control industry. All our products are broken into noise barrier materials – https://www.allnoisecontrol.com/SoundBarriers.cfm and noise absorption materials – https://www.allnoisecontrol.com/NoiseAbsorption.cfm. There are 2 main ways to deal with sound problems.

Noise control is an active or passive means of reducing sound emissions, often incentivised by personal comfort, environmental considerations or legal compliance. Practical and efficient noise control is wholly reliant on an accurate diagnosis of what is causing the noise, which first involves finding the source of noise. Once the source of noise has been found, the focus is reducing the noise at source by engineering means.

Noise Absorption Sound absorbers are soft, porous, open-celled materials such as foam sheets or fiberglass blankets and baffles that reduce the reflection of sound waves. Their sound absorption efficiency is rated by a “NRC” number – Noice Reduction Coefficient*. The HIGHER the NRC rating, the more EFFICIENT the product is at absorbing noise.

*NRC is a sound absorption rating. It measures a percentage of how much sound will not be reflected back from where it came. Based on a range from .05 to 1.0, where a NRC of 1.0 means that all the sound energy that hits that product passes through it and does not “bounce” back to its source. A NRC of .60 would reflect 40% of the sound back to the source and let 60% of the noise pass through it.
